Collect, transport, and store gas and liquid samples without worrying about evaporation or leaks. These syringes have a locking valve that keeps your sample secure. They also have a piston that creates a leak-free, gastight seal against the barrel.

With a glass barrel, these syringes have a long lifespan and aren’t likely to wear or warp from your samples. They have a tighter tolerance than syringes with plastic barrels, so they’re better at controlling small, precise flows. They’ll dispense all material inside with nothing left over—the needle sits exactly at the zero graduation mark, and the piston’s seal against the barrel wipes off any deposits from liquids. With no deposits, the plunger won’t get stuck while dispensing. The piston’s seal is also tight enough that the plunger won’t retract on its own, so you can dispense from these syringes in a slow, controlled manner. Thanks to their precision, these syringes are often used for gas chromatography.

To attach the needle, slide it in at the base of these syringes and secure it with its locking nut. Made of stainless steel, the needle has a smooth surface that limits friction. It’s also sharp and beveled so it can be inserted without clogging or leaving a hole. This makes it ideal for puncturing septa lids.

Use these barrels with an air-powered dispenser to make repetitive dispensing easier on your hands.

Syringe barrels with a luer lock connection require a needle with a luer lock or luer slip connection to dispense contents.

Choose a black syringe barrel to dispense light-activated contents, such as adhesives.

Prevent static from damaging sensitive equipment as you use an air-powered dispenser. These barrels drain static away from your application, so they won’t pass along harmful charges. This makes them ideal for applying adhesives to electronics. Their black color keeps light-activated contents from hardening or curing before use. To dispense, you’ll need a static-control tip with a luer lock or luer slip connection.

Pair these pipettes with a pipette pump to transfer measured streams of liquid. Each pipette has a color-coded band that indicates capacity so you can quickly differentiate one from the next.

Plastic pipettes have a filter to protect their pump from aerosol and splash contamination. Pipette filters are especially important when working with acids and corrosive solutions. Borosilicate and soda-lime glass pipettes withstand cleaning chemicals, so you can sterilize them for repeated use. They provide a clearer view over time than plastic pipettes because samples won't stain them. Soda-lime glass pipettes have extremely tight tolerances to dispense the same amount of liquid each time, keeping your measurements precise. Choose a pipette based on the capacity you need to dispense.

Pipettes with graduation marks let you accurately measure samples of various sizes with a single pipette.

Hold reagents and samples for easy access during pipetting. These reservoirs have an angled bottom, so you can collect samples even as your liquid starts to run low.

Rectangular reservoirs have molded graduation marks to see how much liquid is inside. There’s a pour spout on each corner to discard excess liquid.

V-shape reservoirs have a single large reservoir on one side and 8- and 12-chamber reservoirs on the other. Useful for multi-channel pipettors, the smaller chambers reduce the risk of waste. They’re often used to hold different reagents or ratios and for serial dilutions. Made of polypropylene, they can be autoclaved for reuse.
